Evolution Trends of Wireless MIMO Channel Modeling towards IMT-Advanced

Chia-Chin CHONG, Fujio WATANABE, Koshiro KITAO, Tetsuro IMAI, Hiroshi INAMURA
2009 IEICE transactions on communications  
The main goals of this paper are to summarize the current state of the art, as well as to point out the gaps in the wireless channel modeling works, and thus hopefully to stimulate research in these areas  ...  The performance of MIMO systems is greatly influenced by the spatial-temporal correlation properties of the underlying MIMO channels.  ...  Therefore, a tradeoff between "accuracy" and "simplicity" should be taken into consideration when developing a good channel model depending on the type of system to be evaluated.  ...

Celerity: A Low-Delay Multi-Party Conferencing Solution [article]

X. Chen, M. Chen, B. Li, Y. Zhao, Y. Wu, J. Li
2012 arXiv   pre-print
We believe that an emphasis on low end-to-end delays between any two parties in the conference is a must, and the source sending rate in a session should adapt to bandwidth availability and congestion.  ...  We have implemented Celerity in a prototype system, and demonstrate its superior performance over existing solutions in a local experimental testbed and over the Internet.  ...  With Celerity, we attempt to bridge the long-standing gap between the bit rate of a video source and the highest possible delay-bounded broadcasting rate that can be accommodated by the Internet where  ...
